Around 3 months, your baby will develop a nap schedule.
(True; my baby naps whenever he's so absolutely exhausted from fighting a nap, he just passes out.)
Your baby will take 3 1-2 hour naps a day.
(If by "3" you mean "5," and "1-2 hours," you mean "30-40 minutes." Except when you have visitors who have heard stories about your non-napping baby, at which point, he will sleep for 3 solid hours.)
Putting your baby down drowsy but awake will help him learn to fall asleep on his own.
(It will also help you learn just how much fussing and crying you can tolerate before caving and rocking him or nursing him to sleep like you always do.)
When your baby starts breaking out of his swaddle, it's time to stop swaddling.
(It sure is . . . if you want to watch him slap himself awake repeatedly. Alternately, it's time to wrap him up tighter.)
Baby should nap in his crib, not a car seat, bouncy seat or swing.
(At this point, I don't care if he wants to sleep on the hood of the car . . . )
At 4-6 months, most babies can sleep through the night without feeding, so try to soothe your baby back to sleep instead of nursing him.
(We do this. I soothe him by . . . nursing him.)
